MAGAZINE PENCIL.

Application filed August .18, 1922, Serial To all whom it may cmzcernu Be it known that I, AMBuosn FLEMING, a citizen of the United States,.residing at Alexandria, in the county of Alexandria and State of Virginia, have invented certain new and useful Magazine Pencils, of which the following is a specification.

' My present invention is a magazine pencil of the screw feed type and it primarily has for its objects to provide a pencil the parts of which are so designednnd correlated that they may be assembled without the use of solder, etc., and further to provide a pencil which will be fool proof, i. e., one which functions properly at all times, both in its writing character and in the supplying of leads, one after another, within the capacity of the magazine.

It is another object of the invention to provide a pencil which is of a sturdy construction and cannot get out of order during ordinary use.

In its general nature my pencil comprises a barrel or casing within which a lead receiver and guide is fastened and a magazine for the leads is arranged to fit over a portion of the lead receiver and guide and deliver the leads, one after another, to the receiver upon. turning the magazine, a nose being screwed to the barrel and being so correlated to the magazine that as the nose is unscrewed and screwed up again the magazine will be caused to deliver a lead to the receiver; there is also provided a screw operated push rod which feeds the lead along the receiver through the nose, the screw being operated by a rotatable head in the end of the pencil opposite to the nose, there beingprov'ision whereby to eliminate longitudinal thrusts on the screw when the push rod is at either limit of its stroke.

In its more specific nature the invention furthermore embodies those novel. details of construction, combination and arrangement of parts,'all of which will be fully described and then be specifically pointed, out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a longitudinal section on an enlarged scale of my invention, the parts being in the position Where a lead is ready for writing purposes.

Figure 2 is a view similar to Figure 1, parts being broken away and shown in ele- No. 582,693. Renewed January 27, 1925.

ration, indicating the position of the parts at the time a new lead is delivered into the lead receiver and guide from the magazine.

In the drawings in which like numerals of r ference indicate like parts in all of the figu 'es, 1 is the barrel or casing which contains a partition bushing-2 that is provided with an annular groove 3, the bottom of which is serratedas at 4, see Figure 12, whereby when the barrel 1 is rolled or pressed into the groove 3, as at 26, the bushing 2 will be rigidly and immovably held within the barrel, not only against longitudinal motion but against rot; tion as well.

The bushing 2 is provided with a middle bore in which the lead receiver and guide 8 is tightly fitted by shrinking the bushing-2 on the lead receiver or guide or fastening the same in any other permanent way. The bushing is also provided with an end bore 6 forming a bearing for the end of the feed screw 18, and it also has an end bore 7 forming a bearing-for one end ofthe magazine 32.

8 designates the lead receiver and guide which extends the full length of the barrel 1 and well into the nose 35 of the pencil holder. The lead receiver and guide 8 where it passes through the central bore of'the bushing 2 is unslotted, as at 9, so as to form a. continuous tube in the length of the bore 5. The lead receiver and guide is provided with a lead receiver socket'll. the socket 11 extending the full length of the magazine 32, which will be again rcl'erred to hereinafter.

The lead receiver and guide is provided with an unslotted end which projects through the washer -13 into'the nose of the pencil.

12 designates a key slot in the lead receiver-and guide, in which the key 17 of the push rod 16 is longitudinally movable. At the end of the key slot 12 the lead receiver and guide has a portion removed, as at 13, so that by heating. the tubular member at 14 and bending it as shown in Figure 9 the push rod 16 may be inserted, after which the parts 88 (Figure 9) will again bend into alignment and when cooled down will be as strong as before.

The lead receiver and guide has a slit end for a purpose presently explained.

18 is the feed screw which in the present embodiment of my invention is tubular in charzu-ter and has one end projected into the socket 6 of the bushing 2. I It also has stops 19- at each end of the screw-way so as to engage the sides of the key 17 and prevent longitudinal thrusts of the screw.

when the key 17 is at either end of'the structure. 20 is :1V socketed head which 1s shrunk or otherwise rigidly secured to the screw 18 and by which the screw is turned. The socketed head is shouldered at 21 and has a threaded end 22 over which the cap 2et is screwed and the socket and cap enclose a chamber 23 in which an eraser 25 may be held.

The slit end 15 of the-lead receiver and guide, when the parts are assembled, is upr set or riveted over, see Figure 1, thus hold- 'fastened in theend-oit the barrel 1, oppo site' that having the head, by pressing or turning a groove 42 in the barrel as shown in Figure 1, thus holding the bushing immovable in the barrel. The bushing .27 is also provided with a threaded counterbore and it has a bearing bore 31 for the magazine 32. The magazine 32 is a cylinder having a V-shaped depression or groove 33 to form a cutoff and guide finger for the leads contained in the magazine '(see' Figure 13) and it also has an annular bead 34 which rests against the bushing '27 when the magazine is fitted in place with its end in the bearing socket 7 of the partition bushing 2, see Figures 1 and 2.

The magazine 32. projects into the pencil holder nose 85, one end of which, 36, is provided with a nose bushing 38 while the other end has a pencil outlet 37. The nose bushing 38 has a threaded end 39 to enter the threaded counterbore 30 of the magazine bearing bushing 27. The bushing 83 has a knurled groove 40 into which the nose shell is rolled or pressed, as at 45, to hold the bushing 38 immovable in the nose 35.

43 is a. disk held in the nose by retainguide, assuming the position shown in 'Fig ures 4 and 5. It should be understood, of course, that when the magazine of the pencil is empty-the screw 18 is turned to bring the key 17 back to the'right hand end of the pencil (see Figure'2). In order to feed the loads forwardly the screw 18 is turned in a clockwise direction to move the key 17 toward the nose of the pencil to project as much lead as desired, see Figure 1.

After using up the first load a second one may be supplied by turning the key 17 to the position shown in Figure 2, and while holding the barrel with the indicator 46 uppermost (Figure 2) the nose 35 is unscrewed one complete revolution or more (one being usually sufficient) whereupon a new lead will be dropped into the lead receiver and guide (see Figure 8) after which the nose 35 is screwed home again to the position shown in Figure 11. Then the lead may be advanced by the action of the screw 18 as before. This operation. of supplying the lead receiver and guide with new leads may be repeated again and again until the supply of leads in the magazine have become exhausted.

I wish to call special attention to the fact that in my construction of pencil the parts are all mechanically connected, i. e.. held together without the use of solder, brazing, or the like so therefore there is no danger of the parts separating or pulling apart during the normal usage of the pencil.

From the foregoing description, taken in The leads are inserted in the 1 -magazine around the lead receiver and lot:

connection with the accompanying drawings, it is thought that my invention will be clear to those skilled in the art.
